IMPROVEMENT IN PRESERVING EFFERVESCENT`LIQUIDS.`

Specification forming part of Letters Patent N o. 164,79?, dated .I une 2J, 1875; application filed April 29,1875.

To all whom it may concern:

Be it known that I, JOHN G. L. BoETTonER, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Preserving Eft'ervescent Liquids, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which Figure l is a front elevation, and Fig. 2 is a plan.

Similar letters indicate corresponding parts.

lVIy invention relates to an apparatus for preserving beer and other similar liquids on draft by means of carbonio acid or other reacting agent or gas.

The purpose of my invention is to admit of introducing the gas to the cask or barrel containing the liquid, below the level of the liquid, without forming any hole other than that which receives the faucet, and by this means I avert, to the greatest possible extent, escape or waste of the gas.

My invention consists in the combination of a portable fountain, containing carbonio acid or other gas, with a cask or barrel containing beer or other similar liquid, with a faucet secured to the cash or barrel, and with apipe connecting the fountain with the faucet in such a manner that the gas is introduced to the cask or barrel through the medium ofthe faucet and below the level of the liquid.

In carrying out my invention I take a fountain, A, of the kind commonly used for holding carbonio acid or other similar gas, and fill the same with gas. To any suitable part of the fountain is secured one end of a pipe, B, the other end of which is secured to a fauy cet, C.

linto the cask or barrel E and commingles with the liqiiid contained therein, and by this means the life or fresh state of the beer is preserved after its inherent life has passed oft'.

The faucet I prefer to construct with an autoinaticvalve, which is subjected to the action of the gas and of the liquid when the faucet is secured to the cask, in such a manner that as longas the beer retains its inherent life no gas is allowed to enter the cash, and vice versa. i

It is apparent that by introducing the gas below the level of the liquid in the cash or barrel E a very thorough corniriingling of the gas with the liquid takes place.

I am aware that carbonio-acid gas has been supplied to beer-barrels through a pipe extending down through an opening formed in the side of the barrel, said pipe communicating with a vessel in which the carbonio-acid gas is generated. Such I do not claim, as a close connection cannot be made between the barrel and pipe, and, further7 it requires skill to prepare the gas, and can only be accomA plished by persons skilled in such art. also aware that a pump has been employed in connection with a tube that communicates with the faucet, said pump serving to inject air through the tube and faucet into the barrel. Neither does such demonstrate the spirit of my invention, inasmuch as air is used, and, further, the pu mp requires the attention of an attendant, and unless he be skilled there is danger of the barrel being bursted by too heavy pressure of air being forced into the same. Nor do I claim generating carbonicacid gas in vessels and forcing the same into casks containing beer through a pipe and faucet, as such requires complex arrangement of parts to form the generator; and, further, such vessels are not of a portable character, and skilled persons are required to handle the gas-generating apparatus.

The practicability and novelty of my invention depend upon the fact that the vessel when charged with carbonio acid gas is conveyed to the point where the gas is to be used, and 4when a communication is established between it and the faucet of a cask or barrel containing beer orother liquid, the carbonio-acid gas is'automatically supplied to the barrel, and an even, uniform pressure at I am all times preserved in the casi; or barrel Without requiring the attention of any person-features which cannot be accomplished by the aid of a pump and analogous apparatus.

What I claim as new, and desire to secure by Letters Patent, is-

In an apparatusfor supplying carbonio-acid gas to a vessel containing beer or other liquid to be preserved, the combination of a portable closed vessel in which carboncacid gas is stored, with a pipe and faucet, said pipe eX tending from the vessel containing carbonicacid gas under pressure and connected with the faucet, which is constructed to be secured JOHN G. L. BOETTCHER.
